Seven-day NHS warning for common eczema treatment
It can be used to treat a variety of skin conditions but also runs the risk of a number of side effects
People using certain steroid creams to treat skin conditions have been issued a seven-day warning by the NHS. Hydrocortisone, a commonly prescribed corticosteroid medicine, is used to reduce inflammation and swelling.
It's widely used to treat a range of skin conditions including eczema, contact dermatitis, psoriasis, nappy rash, insect bite reactions, heat rash, and more. While it's usually applied as a cream, ointment or spray, it can also be taken as a tablet for mouth ulcers and adrenal gland conditions, injected for painful joints, and used as suppositories.
Hydrocortisone comes in various strengths, which will be prescribed based on the severity of your condition. The amount you need will also depend on the size of the area you're treating.
How long you should use hydrocortisone for
NHS guidance emphasises that hydrocortisone should not be used on the skin for more than seven days, unless advised by a pharmacist or doctor. This is due to the increased risk of side effects associated with frequent use of topical hydrocortisone.
Side effects can include:
- A rash that may be itchy
- Small red lines (blood vessels) on your skin
- Stretch marks
- Your skin is becoming lighter or darker than usual
- Thinning of the skin in the affected area
More severe side effects associated with topical hydrocortisone can include:
- Weight gain
- A puffy face
- Muscle weakness
- Dizziness
- Hair loss
- Excessive hair growth
- An allergic reaction - rash, difficulty breathing, swollen throat or tongue
- Blurred vision and other vision problems
Weight gain, a puffy face, muscle weakness, dizziness, hair loss, excessive hair growth, allergic reactions such as rashes, difficulty breathing, swollen throat or tongue, and blurred vision are all potential side effects of hydrocortisone. However, it's crucial to remember that if you've been prescribed this medication for a prolonged period, you should continue its use unless advised otherwise by a pharmacist or doctor.
This is due to the skin potentially becoming dependent on the steroid, leading to withdrawal symptoms if abruptly discontinued.
This list doesn't cover all possible side effects associated with hydrocortisone use. If you're currently using this product or have been prescribed it but haven't started yet, the included leaflet should provide more detailed information.
Skin conditions that may need to avoid hydrocortisone
While hydrocortisone is effective at treating a variety of skin conditions, including eczema, there are some conditions where it may not be appropriate. This can include:
- Chickenpox or shingles
- Bacterial skin infections, such as tuberculosis
- Perioral dermatitis (inflamed skin around the mouth)
- Rosacea
- Acne
- Cold sores
If you are suffering from any of these conditions, it is advised that you speak to a pharmacist or GP to help you find the right treatment. Further guidance around hydrocortisone can be found on the NHS website here.
